Ink Smearing on the Paper.

Printhead crashes against the Paper.

Roll Paper loading problems (low probability).
Banding at variable extreme environmental conditions
NOTE: This problem is only applicable if the OMAS is disabled.
Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme
environmental conditions will cause banding because the advance of the Drive Roller does not correspond to
the same conditions that the calibration was done in. To solve the problem, perform the Accuracy Calibration
in the new environmental conditions (see Using your printer).
Printhead crashes/smears on high-density prints using coated
paper
High density prints can cause cockle mainly on HP Coated Paper. This causes two main problems:
1. Cockling in the borders - Because the printer places too much ink on the Coated Paper, the borders of
the print become raised, causing the Printhead to crash against the paper. To solve the problem, try the
following.
●
Change the paper margins to 15mm, either in the Front Panel or in the Driver. If the customer is
printing PostScript images, send them a PPD file containing the extended margins of 15mm.
2. Cockling within the print - If the printer places too much ink within the print, the paper starts to ripple,
causing the Printhead to smear against the paper. To solve the problem, try the following.
●
Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
●
Never use HP Coated Paper for High Density prints. As a substitute use HP Heavy Coated Paper.
Banding due to ink cartridge replacement while printing
A user has removed the Ink Cartridge while the printer was printing, which has caused the printer to stop. If
the user does not replace the Ink Cartridge immediately, when the printer starts to print again, a band will
appear in the position where the printing restarted. This is because the wet ink interacts with the dried ink on
the paper causing the band to appear. To solve the problem, try the following.
●
Do NOT remove the Ink Cartridge while the printer is Printing. Only replace/remove Ink Cartridges in
between Prints.
●
If the Ink Cartridge was replaced due to the “Empty” status on the Front Panel, then advise the
customer to replace the Ink Cartridge when the “Very Low” status is showing on the Front Panel.
●
Reprint the file (without remove the Ink Cartridge).
34" Rice Paper not supported
Roll width is 34" (non-standard), and the pinch wheels can't control the edge of the paper, causing ink smears
and printhead crashes.
